しかし、上記シクロデキストリン類による包摂処理によっても、例えば、EPAなどに由来する魚特有の臭気を完全になくすることは達成されておらず、包括処理後粉末化されても、ゲスト化合物が完全に包摂されないため、長時間の保存によって臭気が増し、ときには着色度が増加するなどの問題があった。   However, even by inclusion treatment with the above cyclodextrins, it has not been achieved to completely eliminate the odor peculiar to fish derived from EPA, for example.

And obtaining a second mixture of γ-cyclodextrin, wherein the low molecular weight polysaccharide consists of about 16 D-glucose and comprises about 6 D-glucose homoglucose chains. It has a spiral structure as a unit.

本明細書で用いる用語「臭い成分または苦味成分」は、制限されずに、ドコサヘキサエン酸(DHA)、エイコサペンタエン酸(EPA)およびビタミンE(VE)、α−リポ酸DHA誘導体、EPA誘導体、ビタミンEおよびその誘導体、その他n−3系およびn−6系脂肪酸とその誘導体などの人によっては嫌われるいわゆる魚臭さを呈する成分、ならびに酸化されやすく、酸化されることによって不快な臭いを発生する成分(本明細書では、有臭物質または無臭化対象物とも称される)、あるいは、田七人参抽出物、苦丁茶のカテキン含有組成物、ギムネマ・シルベスタ抽出物、ニガウリの抽出物、イソフラボン、グアバフェノンなどの苦味成分、トウガラシの辛味成分を包含する。   The term “odor component or bitter component” as used herein is not limited and includes docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA) and vitamin E (VE), α-lipoic acid DHA derivative, EPA derivative, vitamin E and its derivatives, other components such as n-3 and n-6 fatty acids and their derivatives, which exhibit a so-called fishy odor that is hated by humans, and are easily oxidized and generate unpleasant odors when oxidized Ingredients (also referred to herein as odorous substances or non-brominated objects), or Tanachi ginseng extract, bitter tea catechin-containing composition, Gymnema sylvestre extract, bitter gourd extract, isoflavone , Bitterness ingredients such as guavaphenone, and pungent ingredients of pepper.

上記分子量約3,000の低分子多糖類は、ホモグルコースからなる水溶性多糖類であり、例えば、デンプンから調製され得、好ましくは、螺旋の1巻きがD−グルコース残基6個からなる右巻き螺旋構造を有し得、その結果、その螺旋の中央にヨウ素分子Iが取り込まれてヨウ素呈色反応で発色するような構造を有している。このような低分子多糖類は、例えば、備前化成株式会社(岡山県赤磐市徳富363)からポタコーゲン(登録商標)として市販され入手可能である。 The low-molecular-weight polysaccharide having a molecular weight of about 3,000 is a water-soluble polysaccharide composed of homoglucose, and can be prepared from, for example, starch. Preferably, one spiral is composed of 6 D-glucose residues. It may have a wound spiral structure, and as a result, it has a structure in which iodine molecule I 3 is taken into the center of the spiral and develops color by iodine coloring reaction. Such a low-molecular-weight polysaccharide is commercially available as, for example, Potacogen (registered trademark) from Bizen Kasei Co., Ltd. (363 Tokutomi, Akamine, Okayama Prefecture).

特定の理論に拘束されることは意図されないが、臭い成分または苦味成分などのゲストが完全にマスクされるのは、以下のように考えられる。   While not intending to be bound by any particular theory, it is believed that a guest such as an odorous or bitter component is completely masked as follows.

γ−CDは環状化合物であり、環内に対象となる化合物を包摂して包摂体を形成する包摂化合物の代表物質である。一方、ポタコーゲン(登録商標)はデンプンから調整した分子量約3,000のホモグルコースからなる水溶性の低分子多糖体であって、デンプンのヨウ素呈色反応はデンプンがD−グルコース残基6個からなる右巻き螺旋構造をとり、その螺旋の中央にヨウ素分子Iが取り込まれて発色するようにわずかに包摂能を有している。ポタコーゲン(登録商標)は分子量約3,000であるが、デンプンは分子量2〜3百万の巨大分子であり、両者の螺旋構造を比較すると、ポタコーゲン(登録商標)の螺旋構造はデンプンのそれに比較して非常に粗であって緩やかであり、例えばDHAでさえもその螺旋構造中に包摂されると考えられる。このようなポタコーゲンの構造が、γ-CDと相互作用し、苦味成分および臭い成分などの非包摂物質を包摂する能力を向上すると考えられる。 γ-CD is a cyclic compound, and is a representative substance of an inclusion compound that includes an object compound in the ring to form an inclusion body. On the other hand, Potacogen (registered trademark) is a water-soluble low molecular weight polysaccharide consisting of homoglucose having a molecular weight of about 3,000 prepared from starch, and the iodine coloring reaction of starch is based on 6 D-glucose residues in starch. The right-handed spiral structure is taken, and the iodine molecule I 3 is taken into the center of the spiral and has a slight inclusion ability so as to develop color. Potacogen (registered trademark) has a molecular weight of about 3,000, but starch is a macromolecule having a molecular weight of 2 to 3 million. When comparing the helical structure of both, the helical structure of Potacogen (registered trademark) is comparable to that of starch. Thus, it is considered to be very coarse and gentle, for example even DHA is included in the helical structure. Such a structure of the potacogen is considered to interact with γ-CD and improve the ability to include non-inclusion substances such as bitter components and odor components.

従って、有臭のDHAEを例にして説明すると、DHAEの構造の一部がポタコーゲン(登録商標)に包摂され、次いでポタコーゲン(登録商標)との包摂体がγ−シクロデキストリンに包摂されてDHAEの無臭化物が完成されると考えられる。   Therefore, taking odorous DHAE as an example, a part of the structure of DHAE is included in Potacogen (registered trademark), and then an inclusion body with Potacogen (registered trademark) is included in γ-cyclodextrin and It is thought that the bromide is completed.

本明細書で用いる用語「包摂」は、特定成分の分子が、適切な条件下で組みを合わさって、他の分子がつくったトンネル型、層状または網状構造の隙間に入りこんむことをいい、他の分子は、代表的には、γ-CDとポタコーゲン(登録商標)との組み合わせである。   As used herein, the term “inclusion” refers to the entry of molecules of a particular component into a tunnel-type, layered, or network-like gap created by other molecules when combined together under appropriate conditions. This molecule is typically a combination of γ-CD and Potacogen (registered trademark).

本発明は、ポタコーゲン(登録商標)の包摂能とγ-CDの包摂能との組み合わせによりその協同作用および/または相乗作用によって、DHAなどの苦味成分および臭い成分をそれぞれ単独で用いるより完全に包摂し、向上した包摂能によって無臭化および無味化できると考えられる。従って、この意味で、ポタコーゲン(登録商標)は、「包摂補助剤」と称され得る。   The present invention provides a more complete inclusion by using a combination of the inclusion ability of Potacogen (registered trademark) and the inclusion ability of γ-CD, and its bitter and odorous components such as DHA alone, due to their cooperative and / or synergistic effects. However, it is thought that it can be made non-brominated and tasteless by the improved inclusion ability. Therefore, in this sense, Potacogen (registered trademark) can be referred to as an “inclusion aid”.

上記低分子多糖類は約3,000の分子量を有し得、上記第1の混合物を得る工程は0.1〜20重量%濃度の前記低分子多糖類の存在下で行われ、そして上記第2の混合物を得る工程は0.01〜30重量%濃度の臭い成分または苦味成分、および0.01〜30重量%濃度のγ−シクロデキストリン存在下で行われ得る。   The low molecular weight polysaccharide may have a molecular weight of about 3,000, the step of obtaining the first mixture is performed in the presence of the low molecular weight polysaccharide at a concentration of 0.1 to 20% by weight, and the first The step of obtaining a mixture of 2 can be carried out in the presence of an odorous or bitter component at a concentration of 0.01 to 30% by weight and a γ-cyclodextrin at a concentration of 0.01 to 30% by weight.

上記第2の混合物は、さらに、フリーズドライによって粉末体とされ得るか、または、適当量のデキストリン加えて攪拌均一化してからフリーズドライによって粉末体され得る。フリーズドライに代えて、当該技術分野で公知の、飽和水溶液法、混練法、混合粉砕法などによっても上記第2の混合物は、粉末体にされ得る。   The second mixture may be further powdered by freeze drying, or may be powdered by freeze drying after adding a suitable amount of dextrin and stirring and homogenizing. Instead of freeze-drying, the second mixture can be formed into a powder body by a saturated aqueous solution method, a kneading method, a mixing and pulverizing method and the like known in the art.

なお、回収DHAE量は、遠心分離の上澄液に残存するDHAE量であって、上澄液を乾燥して測定したDHAE重量である。   The recovered DHAE amount is the amount of DHAE remaining in the supernatant of centrifugation, and is the DHAE weight measured by drying the supernatant.


これらの一連の包摂反応の結果、ポタコーゲン(登録商標)とγ-シクロデキストリンとの重量比が約(1:1)の組み合わせにおいて、DHAEの包摂体が水溶液中に白色の沈殿を生成することが見出された。この白色包摂体は、DHAEの添加量に依存して無臭〜有臭を呈し、包摂体中のDHAE含量が高いほど(データは示さず)臭いが強い傾向にあり、包摂収率100%が得られる組み合わせが包摂体が無臭である限界であることが明らかになった。表1に示す結果から明らかなように包摂収率100%が得られる組み合わせは、DHAEと包摂化剤(γ−CD+ポタコーゲン(登録商標))との重量比は1:2であった。

As a result of these series of inclusion reactions, the inclusion of DHAE can produce a white precipitate in an aqueous solution in a combination of about 1: 1 weight ratio of Potacogen (registered trademark) and γ-cyclodextrin. It was found. This white inclusion body is odorless to odorous depending on the amount of DHAE added, and the higher the DHAE content in the inclusion body (data not shown), the stronger the odor tends to be, and an inclusion yield of 100% is obtained. It was revealed that the combination that was made was the limit that the inclusions were odorless. As is apparent from the results shown in Table 1, the weight ratio of DHAE and the inclusion agent (γ-CD + Potacogen (registered trademark)) was 1: 2 in the combination that gave an inclusion yield of 100%.


(実施例2)
上記のDHAE包摂反応における包摂化剤であるγ−CDおよびポタコーゲン(登録商標)の添加順序を変えることによって、包摂体に取り込まれるDHAE含量が影響を受けるか否かを検討した。

(Example 2)
It was examined whether or not the DHAE content incorporated into the inclusion body was affected by changing the order of addition of γ-CD and Potacogen (registered trademark) as inclusion agents in the above DHAE inclusion reaction.

DHAE量は一定とし、γ−CDとポタコーゲン(登録商標)の重量比は2:1として、γ−CDとポタコーゲン(登録商標)の添加順序を変えた時の包摂体に取り込まれるの推定DHAE含量を算出した。反応はいずれも、実施例1と同様に窒素で満たされた容器中で行った。結果を表2に示す。   Estimated DHAE content incorporated into inclusion bodies when the DHAE amount is constant and the weight ratio of γ-CD to Potacogen (registered trademark) is 2: 1 and the order of addition of γ-CD and Potacogen (registered trademark) is changed Was calculated. All the reactions were performed in a container filled with nitrogen as in Example 1. The results are shown in Table 2.


表2.γ−CDとポタコーゲン(登録商標)の添加順序を変えたときに包摂体に取り込まれる推定DHAE量

添加順序 包摂体の推定DHAE含量
γ−CD → DHAE → ポタコーゲン(登録商標) 39.9%
ポタコーゲン(登録商標) → DHAE→ γ−CD 84.2%
ポタコーゲン(登録商標) → DHAE→ γ−CD 97.0%
ポタコーゲン(登録商標) → DHATG → γ−CD 85.9%
ポタコーゲン(登録商標) → DHAF → γ−CD 106.0%

表2において、包摂体中に取り込まれた推定DHAE量は、γ−CD、DHAEおよびポタコーゲンの添加量の合計量から、生成された包摂体量の差を未包摂DHAEとし、この値をDHAE添加量から差し引いた値と、γ−CDとポタコーゲン(登録商標)の和の商から算出した値である。

Table 2. Estimated amount of DHAE incorporated into inclusion bodies when the order of addition of γ-CD and Potacogen (registered trademark) is changed

Order of addition Estimated DHAE content of inclusions γ-CD → DHAE → Potacogen (registered trademark) 39.9%
Potacogen (registered trademark) → DHAE → γ-CD 84.2%
Potacogen (registered trademark) → DHAE → γ-CD 97.0%
Potacogen (registered trademark) → DHATG → γ-CD 85.9%
Potacogen (registered trademark) → DHAF → γ-CD 106.0%

In Table 2, the estimated DHAE amount incorporated into the inclusion body, gamma-CD, the total weight of the amount of DHAE and Potakogen, the difference of the generated subsumer Weight and non inclusion DHAE, this value It is a value calculated from the value subtracted from the DHAE addition amount and the quotient of the sum of γ-CD and Potacogen (registered trademark).

この結果、先ず、DHAEをポタコーゲン(登録商標)と反応させた後にγ−CDと反応させる方法(推定DHAE含量84%以上)が、DHAEをγ−CDと反応させた後にポタコーゲン(登録商標)と反応させる方法(推定DHAE含量40%)よりDHAEが高率で包摂されることが明らかになった。   As a result, first, a method in which DHAE is reacted with Potacogen (registered trademark) and then reacted with γ-CD (estimated DHAE content of 84% or more) is obtained by reacting DHAE with γ-CD and Potacogen (registered trademark). It was revealed that DHAE was included at a higher rate than the reaction method (estimated DHAE content 40%).

また、DHAEに代えて、DHATGまたはDHAFを用いて上記と同様の試験を行ってところ、表2に一部結果が示されるように、DHAEと同様に、最初にDHATGまたはDHAFをポタコーゲン(登録商標)と反応させた後にγ−CDと反応させる方がこれら物質が高率で包摂されることが見出された。   In addition, when a test similar to the above was performed using DHATG or DHAF instead of DHAE, as shown in Table 2, some of the results are shown. First, as with DHAE, DHATG or DHAF is first converted to Potacogen (registered trademark). It has been found that these substances are included at a higher rate when reacted with γ-CD after reacting with.


(実施例3)
本実施例では、包摂反応における適正なDHAE含量を検討した。DHAEとγ−CDとポタコーゲン(登録商標)との反応順序は、実施例2に示される結果に従ってDHAEをポタコーゲン(登録商標)と反応させた後にγ−CDと反応させ、かつDHAEを暫時増量してその生成される包摂体の重量を求め、そしてその形態を比較した。結果を表3に示す。

Example 3
In this example, the appropriate DHAE content in the inclusion reaction was examined. The reaction sequence of DHAE, γ-CD and Potacogen (registered trademark) was determined by reacting DHAE with Potacogen (registered trademark) and then reacting with γ-CD according to the results shown in Example 2, and increasing the amount of DHAE for a while. The resulting inclusions were weighed and their forms were compared. The results are shown in Table 3.

なお、ポタコーゲン(登録商標)とγ-CDとの重量比は1:3とした。表3においてPoGはポタコーゲン(登録商標)を表し、そしてDHAE含量は、DHAE重量/(DHAF重量+ポタコーゲン(登録商標)重量+γ−CD重量)である。   The weight ratio of Potacogen (registered trademark) and γ-CD was 1: 3. In Table 3, PoG represents Potacogen (registered trademark), and the DHAE content is DHAE weight / (DHAF weight + Potacogen (registered trademark) weight + γ-CD weight).

ポタコーゲン(登録商標)5.0gとDHAE(80%含量)6.7gと蒸留水75mLを300mLナスフラスコに採り、窒素を満たして密栓して、スターラー上で室温下に1時間攪拌する。その後、d−α−トコフェロール0.8gとγ-CD15gを入れて攪拌すると短時間で黄白色の固形物が形成された。フリーズドライ粉末にするとパサパサの無味無臭の帯電体黄色粉末となった。

Example 4
Potacogen (registered trademark) 5.0 g, DHAE (80% content) 6.7 g and distilled water 75 mL are put into a 300 mL eggplant flask, filled with nitrogen, sealed tightly, and stirred on a stirrer at room temperature for 1 hour. Thereafter, when 0.8 g of d-α-tocopherol and 15 g of γ-CD were added and stirred, a yellowish white solid was formed in a short time. When it was freeze-dried, it became a tasteless and odorless charged yellow powder of papasa.

一般に、本発明の方法によって得られた臭い成分または苦味成分の包摂体は、d−α−トコフェロールのように、被包摂対象物が有色である場合、包摂体中の被包摂対象物の濃度が増加するにつれて白色から淡い有色になった。   In general, the inclusion body of the odor component or bitterness component obtained by the method of the present invention has a concentration of the inclusion object in the inclusion body, such as d-α-tocopherol, when the inclusion object is colored. As it increased, it turned from white to light colored.


(実施例5)
表3に示される結果から、DHAE20〜30%以下の含有の包摂物が白色無臭品であったことから、DHAE包摂物の安定性とコストダウンを計るためにポタコーゲン(登録商標)とγ-CDとの量比を調べるためと他の賦形剤(デキストリン)を混合した場合の粉末の形態を調べた。まず実施例3と同様の手順を用い、表4に示す量でDHAEと包摂化剤を用いて包摂反応を行った。

(Example 5)
From the results shown in Table 3, since the inclusion containing DHAE 20 to 30% or less was a white odorless product, in order to measure the stability and cost reduction of the DHAE inclusion, Potacogen (registered trademark) and γ-CD In order to examine the ratio of the amount and the other powder (dextrin), the powder form was examined. First, using the same procedure as in Example 3, an inclusion reaction was performed using DHAE and an inclusion agent in the amounts shown in Table 4.
